ASCII	ESC * m n1 n2 d1 ... dn
Hexadecimal	1B 2A m n1 n2 d1 ... dn
Decimal	27 42 m n1 n2 d1 ... dn
Value of m:
Value of m	Mode	No. of dots (vertical)	No. of dots (horizontal)	No. of dots/line
0	8-dot single-density	8 (68 DPI)	0–288 (101 DPI)	8 x 288
1	8-dot double-density	8 (68 DPI)	0–576 (203 DPI)	8 x 576
32	24-dot single-density	24 (203 DPI)	0–288 (101 DPI)	24 x 288
33	24-dot double-density	24 (203 DPI)	0–576 (203 DPI)	24 x 576

Value of n:

Value of n (8-dot single-density mode)	Value of n (24-dot single-density mode)	Value of d
n1 + (256 x n2)	3 x [n1 + (256 x n2)]	Number of bytes of data*

*Printed left to right (8-dot mode); printed down then across (24-dot mode)

Formulas

8-dot single-density= n1 + (256 X n2)

24-dot single-density= 3 X [n1+ (256 X n2)]

Sets the print resolution and enters one line of graphics data into the print buffer. Excess data is accepted but ignored. Any print command is required to print the data, after which the printer returns to normal processing mode.

See the illustration for graphic representations of the bit image below.
